Uhhh, I hope I did not corrupt the code in Codeplex. Sorry!!!

Looks OK to me!

I see you've merged twice, so the graph looks a little untidy, but I'm not too fussy about that

It's a good idea to pull any changes from the repository before committing and pushing an update, then it's less likely you'll have to do any merging.

Puuhh, I was worried about the lots of files pushed to codeplex. Does this mean, that all files on my local directory, which are changed by a merge , will be pushed to Codeplex even if I dont change them? I only changed deutsch.aslx

I think the changes to lots of files was probably just to bring your "branch" into line with the main one, so I wouldn't worry. You can always check that your merge is OK before pushing to Codeplex - run the unit tests!

how do I run the unit tests?

This seems to be a screenshot of VisualStudio? But I dont work with VS. Its not possible to install it on my PC

Yes the unit tests are part of the source code so run in VS.

If you're not using VS you probably don't need Developer permissions on CodePlex, you could just send me pull requests to update Deutsch.aslx?

OK, I will try to execute a pull request.
